Differences in Yield and Population Structure Among Different Varieties of Wheat Grown After Rice in Gaoyou City

通过11个稻茬小麦品种产量及群体特征比较试验,结果表明:从生育期来看,扬麦23熟期最早,仅201 d,镇麦11号、镇麦12号成熟期最迟,达208 d;从产量来看,镇麦12号产量最高,达531.0 kg/667 m^2,其次为扬麦25和扬麦23,产量分别为528.7、513.7 kg/667 m^2,产量最低的为国红6号,为417.3 kg/667 m^2。穗数最高的是扬麦25,达34.5万个/667 m^2,最低为国红6号,为27.0万个/667 m^2;从每穗粒数来看,粒数最多为扬麦25,达42.8粒/穗,最少的为宁麦13,仅37.4粒/穗;从千粒质量来看,最高为镇麦12号,达46.3 g,最低为苏麦188,仅38.9 g。

In order to select wheat varieties suitable for planting in central areas of Jiangsu Province,this study compared eleven wheat varieties with respect to yield and population structure.These varieties are widely used in wheat production,comprising Yangfumai 4,Sumai 8,Sumai 11,Sumai 188,Guohong 6,Yangmai 25,Ningmai 13,Yangmai 22,Zhenmai 11,Zhenmai 12,and Yangmai 23.The results showed that Yangmai 23 had the shortest growth period being only 201 days,while Zhenmai 11 and Zhenmai 12 had the latest maturity,with the growth periods up to 208days.In terms of yield,Zhenmai 12 attained the highest yield reaching 531.0 kg/667 m2,followed by Yangmai 25 and Yangmai 23,with yields of 528.7 and 513.7 kg/667 m^2,respectively,whereas Guohong 6 had the lowest yield of 417.3 kg/667 m^2.Moreover,Yangmai 25 had the highest panicle number(345000 panicles/667 m^2),while Guohong 6had the lowest paniclenumber(270000 panicles/667 m^2).Regarding grain number per panicle,Yangmai 25 had the highest number of 42.8 grains/panicle,whereas Zhenmai 11 had the lowest(38 grains/panicle).In terms of 1000 grain weight,Zhenmai 12 had the highest(46.3 g),while Sumai 188 had the lowest(38.9 g).
